A `public-only` token with `write:package` scope, whose owner can read a private package and write to a public package namespace, could mount a blob of the private package into the public package. The private blob, such as a container layer, could then be downloaded by anyone through the public package.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-28.3.0/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39690","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39853","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8g99-g36h-5p2w","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39690","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39853","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-8g99-g36h-5p2w","tags":[]}],"hasPoc":true,"ai":null}
